This new tool mode is designed for working with the Motion Tracker. It replaces the previous 2D and 3D View commands and is positioned prominently as an icon in the Motion Tracker layout (directly above the Attribute Manager).

Enabled: Work with 2D Tracks (show footage, set, move Tracks, etc.; only works in the Perspective view). The enabled view will be shown in the Viewport with a yellow frame. The keyboard shortcuts such as Ctrl/Cmd + a (select all Tracks), H to show all footage, directional arrows to move selected Tracks and normal selection tools such as Live or Rectangular Selection.

This mode will be automatically enabled when a Motion Tracker object is created or if you double-click on an existing Motion Tracker object.

Disabled: Work with 3D elements of the Motion Tracker: the 3D features will be shown and can be selected, for example. When disabled, the original 3D modus will be reverted to (i.e., prior to activating 2D Tracks).
